The relation between land subsidence and CO2 emission in peatlands

There are two crucial factors that need to be considered when using land subsidence data to establish CO2 emissions from drained peatlands: i) not all land subsidence is the result of microbial decomposition of peat, and ii) a conversion value to express land subsidence (volume change) in CO2 emissions (mass). This paper assesses how previous studies have dealt with these two factors and supplements existing values and experiences with new data and insights gathered over the last couple of years.
